Sapphire driver?

Just installed 10.5 Pro and my audio recognizes Focusrite Sapphire 6 USB in its dropdown. But when I try to assign it as my audio choice I get a message saying the unit is not connected correctly to the computer. It’s the sound choice for the computer itself and Sound Forge, but Cubase won’t let me load it in as audio preference. Anybody know if there’s a specific driver update that will allow Cubase to let it in?

is this mac or pc? could it be as simple as Soundforge is open with asio drivers so Cubase can’t use it?
